World tuna stocks not up to MSC standards

New report says just 6 of 19 major tuna stocks are being managed to prevent overfishing.

Just more than 30 percent of the world's major commercial tuna stocks are being managed to avoid overfishing and restore depleted fish populations, according to a report published by the International Seafood Sustainability Foundation (ISSF).

The study also said the majority of the stocks are not protected by well-defined harvest control rules (HCRs) from Regional Fishing Management Organizations (RFMOs),

In the December 2016 version of the report, almost twice as many stocks -- 11 of 19 -- were found to be well managed. This variance can be attributed in part to refinements made in 2017 regarding how the Marine Stewardship Council (MSC) standard assesses harvest control rules, ISSF said.

The report scores stocks against certain components of the MSC standard, and has been updated three times since first published in 2013.

It scores the main commercial tuna stocks -- bigeye, yellowfin, albacore and skipjack (but not bluefin) and each tuna RFMO.
